IMPLEMENT FOR BRUSHING AND SCRAPING SHIPS HULLS.

SPECIFICATION Forming part of Letters Patent No. 333,503, dated January5, 1886.

Application filed March 730, 1885.

T0 at whom it may concern:

Be it known that' I, CHARLES G. Gnoss, a subject of the Queen of GreatBritain, residing at 10 Olitheroe street, Slade Lane, Longsight,Manchester, England, have invented a new and useful Combined Brush andScraper for Removing Barnacles and Cleaning the Hulls of Vessels, ofwhich the following is a specification.

My invention relates to improvements in brush and scraper for removingbarnacles and cleaning the hulls of vessels while on a voyage at sea.

Figure l is a side elevation of a ship, showing the mode of arranging myimproved combined brush and scraper when in the act of scraping thehull. Fig. 2 is a side elevation, Fig. 3 a plan view, Fig. 4 alongitudinal section, and Fig. 5 a perspective view, of my improvedcombined brush and scraper, showing the construction and generalarrangement of the same.

The following is the construction of the same: I generally form theframe A of wood, and in the center longitudinally I place the metalliccrossbar B, to which I attach the metal standard 0. In thecenter, tothis metal standard 0, I attach the upper cross-bar, D, and rivet thepressure-board E to the same. I attach the clevis F to the turtle-backor pressure-board E and to the frame A under the longitudinal centralframe-piece, G, which is framed into the forward rail of the woodenframe A and extends back to the central crossbar, B, where itisjoined tothe cross-bar Band the central standard, 0. I form the propelling H andI of sheet metal, and connect them by the upper connecting-rods, J, andthe lower connecting-rods, K, and the vertical end pi vot-bars, L, andby the central pivot-bars, M, which are attached to the guidepins Hand Iabout in the center with journals at the top in the upper cross-bar, N,and at the bottom to the central cross-bar, B. I attach the brushes 0and P to the side rails of the frame A by means of screws, so as to betaken off when it is required. I construct the brushes of bamboo ormetal or any other suitable material. Iattach the metal scrapers Q to aheavy india-rubber strip, Y, which I attach to the body or wooden backof the Serial No. 160,634. (No model.)

brush by means of screws, first placinga heavy sole-leather strip, It,and a thin metal plate, S, (to serve as a washer'strip,) under thescrewheads.

In order to show-clearly the operation of my combined brush and scraper,Ihave shown, Fig. 1, a side elevation of a ship with a wire, S, passedout through the hawse-pipe and down under the ship for the purpose ofcarrying the bulls-eye T to serve as a guide for the. guy U, which isattached to the clevis F. I attach the regulating and directing wires Vin the eyes or staples W. The water-line is indicated by theline X. Thecombined scraper and brush is let down by the regulating and directingwires V. As soon as it enters the water, the turtle-back orpressure-plate E, standing at an angle and being carried swiftly throughthe water, is borne closely to the hull of the vessel, so that thescrapers and brushes touch the same. The rear wire V is then raised andthe forward wire lowered, and the action of the water upon theguide-fins H and I carries the same downwith great force, and thescrapers take off the barnacles and other accumulations from the hull,and the brushes complete the process of cleaning. By this arrangementthe bottom is readily reached, and thus every portion of the hull iscleaned. WVhen the scrapers and brushes have been let down as far as itis desired to clean at one operation, then the rear regulating and directing wire V is lowered, while the forward one is drawn up, thusreversing the angle of the guide-fins H and I, and the action of thewater forces the scraper upward.

I generally construct the combined scraper and brush about four feet inlength, and I let it back about two feet at each motion up and. down thehull. Thus every part is gone over twice, once in an upward and once inadownward direction. The scraper, Q, being attached by means of theindia-rubber strip Y, give back when met by an unyielding substance, thebrushes allowing them to incline to an angle that will allow them topass over the edge of an iron plate or other part of the structure.

Thefins H and I are set back from the edge of the brushes to allow thebrushes to pass close to the keel of the ship.

tween the scrapers and the frame, pressure-board, as set forth.

with the frame, of fins 2. The combination,

pivoted to said frame midway their ends and connected at their ends bybars J K, the inclined pressure-board E, the brushes secured to theunder side of the frame, the scrapers secured to the sides of the frame,and the I 5 elastic strips under the scrapers, as set forth.
